Find the perimeter and area of a rectangular envelope with a length of 4 inches and a width of 8 inches.

Step-by-step explanation:

Since the envelope is a rectangle

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

Area of a rectangle = length × width

From the question

l = 4 inches

w = 8 inches

For the perimeter

P = 2(4) + 2(8)

= 8 + 16

We have the final answer as

For the area

A = 4 × 8

We have the final answer as

Hello there!

First, solve the parentheses.

( 5 + 4 - 2 ) = (9 -2)

9 - 2 = 7

Lastly, multiply them by the remaining value : -2.

7 x -2 = -14

Therefore, your answer would be B. -14
